MAX2059

www.DataSheet4U.com 19-0566; Rev 0; 7/06 KIT ATION EVALU E L B AVAILA 1700MHz to 2200MHz High-Linearity, SPI-Controlled DVGA with Integrated Loopback Mixer General Description The MAX2059 high-linearity digital-variable-gain amplifier (DVGA) is designed to provide 56dB of total gain range and typical output IP3 and output P1dB levels of +31.8dBm and +18.4dBm, respectively. The device is ideal for a variety of applications, including single and multicarrier 1700MHz to 2200MHz DCS 1800/PCS 1900 EDGE, cdma2000®, WCDMA/UMTS, and TD-SCDMA base stations. The MAX2059 yields a high level of component integration, which includes two 5-bit digital attenuators, a two-stage driver amplifier, a loopback mixer, and a serial interface to control the attenuators. The MAX2059 is pin compatible with the MAX2058 700MHz to 1200MHz DVGA, facilitating an easy design-in for applications where a common PC board layout is used for both frequency bands. The MAX2059 is available in a 40-pin thin QFN package with an exposed paddle. Electrical performance is guaranteed over a -40°C to +85°C temperature range. ♦ +31.8dBm Typical Output IP3 ♦ +18.4dBm Typical Output 1dB Compression Point ♦ 1700MHz to 2200MHz RF Frequency Range ♦ 700MHz to 1200MHz RF Frequency Range (MAX2058) ♦ 10.9dB Typical Small-Signal Gain ♦ Includes Two Independent 5-Bit Digital Attenuator Stages, Yielding 56dB of Total Gain-Control Range with 1dB Steps ♦ 3-Wire SPI™/MICROWIRE™ Compatible ♦ Integrated Loopback Mixer for Tx/Rx SelfDi...
